FRONT END SUSPENSION FdR VEHICLES Filed Feb. 25. 1937 Patented Apr. 5, 1938 UNITED STATES PATENT OFFICE FRONT nun SUSPENSION FOR VEHICLES Mayer Leonard Oppenheimer, Baltimore, Md. Application February 25, 1937, Serial No. 127,604

Figure l is an elevation of the front end of the chassis of an automobile showing my invention applied thereto.

Figure 2 is a top plan view of Figure 1.

Figures 3, 4 and 5 are plan views of the three control arms, each having a spring seat thereon.

Figure 6 is an enlarged detail view of one of the toggle joints.

Figure '7 is an enlarged detail view of one of the tension springs.

There are two sets of control arms and springs, one for each of the front wheels, and as each set is identical in construction and operation, the description of one set will be sufficient for the purpose of this specification.

Referring to the accompanying drawing, forming part of this specification, and in which like reference numerals designate like parts throughout the several views thereof, I designates the chassis of an automobile and 2 the front wheels thereof.) The wheels 2 are mounted on the upthe chassis I. The lower control arm 6 is pivotally connected at one end to the lower end of the upright 3 and its opposite end pivoted to an arm I of the toggle joint 8, the other arm 9 of the toggle joint 8 is secured to the under side of the chassis I. The said control arm 8 is provided with the spring seat I. The control arms II and I2 are pivotally connected at their outer end and the inner end of the arm II is plvotally connected to the arm I of the toggle joint 8 and the inner end of the arm I2 is connected to the arm 9 of said toggle joint 8. The arm I is provided with a shoulder [3 to limit the expanding movement of the arms I and 9. The control arms II and I2 are provided with spring seats I4 and I 5, respectively. Between the control arms 8 and II is a compression spring I'8 resting in the seats l0 and H and normally exerting its pressure to keep said arms apart, and between the arm I2 and the chassis I is another compression spring i'I "resting in the seat I5 and normally exerting 2 Claims (01. 267-20) its pressure against said control arm I2. Between the inner ends of the control arms II and I2 is a tension spring l8 resting on the seats I8 and 28 and having its ends threaded and projecting through the apertures 2| and 22 and having a nut on each end, which keeps the inner ends of the control arms II and [2 in their proper relative position.

When the wheel 2 strikes a rise in the road it compresses the springs l8 and I! and at the same time the arm 8 pulls on the arm I of the toggle joint 8 forcing the arms I and 8 apart against the action of the tension spring I8, and should the wheel drop into a depression in the road the chassis will remain level on account of the action of the springs l8 and I1.

Having thus described my. invention, what I claim is:

1. A front end suspension for vehicles comprising two units each comprising an upright to which the front wheels are pivoted, an arm connecting the upper end of said upright with the frame of the vehicle, a toggle joint having one arm thereof pivoted to the vehicle frame, an

arm pivoted at one end to the lower end of said upright and its opposite end pivoted to one arm of the toggle joint, two control arms having their outer ends pivoted together and the upper one of which is pivoted at its inner end to one arm of the. toggle joint and the other pivoted to the other arm of said toggle joint, a compression spring between the frame and the outer end of the upper control arm, a compression spring between the outer end of the central control arm and the lower control arm, and a tension spring between the inner ends of the upper and central control arms.

2. A front end suspension for vehicles,'comprising two units each having an upright to which the front wheels are pivoted, a shock absorber secured to the upper surface of the vehicle frame,

an arm connecting the upper end of the upright arm, a compression spring between the outer I ends of the central control arm and the lower control arm, and a tension spring between the inner. ends of the upper and central control arms.
